All the signs of incipient activism and uprising, from Tahrir square to Zuccotti Park to [the recent] shutdown of the Internet to protest web censorship. People are getting smart and getting connected.

Solar power seems to be truly bipartisan in its appeal.

When you are in a hole, stop digging!

Fossil fuel is very seductive stuff. [John Maynard] Keynes once said that, as far as he could tell, the average standard of living from the beginning of human history to the middle of the eighteenth century had perhaps doubled. Not much had changed, and then we found coal and gas and oil and everything changed. We're reaping the result of that, both ecologically and socially.

I try not to be either optimistic or pessimistic. I try not to think about outcomes on that scale. My job, it seems to me, is to wake up every morning and figure out how to cause as much trouble for the fossil fuel industry as I can.

There's no huge mystery. If you dig up huge amounts of carbon, huge amounts of ancient biology, hundreds of millions of year's worth of ancient biology, and flush it into the atmosphere in a matter of decades, then it stands to reason that we're going to have enormous effects, and now we can see those effects all around us.

I did very much like [Barack] Obama's attack on fossil fuel subsidies for fossil fuel companies. We asked for that in demonstrations and petitions, and now we'll try to push it forward.
